TO ALL WHOM IT MAY CONCERN:

Be it known that I, NICHOLAS DOWNES, of Syracuse, in the county of Onondaga, and State of New York haveinvented anew and improved Heat-Radiator; and I do hereby declare that the following is a full clear, and exact description thereof, which will ena-ble those skilled in the art to make ,and usc thcsame rcierenc( being had to the accompanying drawings forming a part'of this specification, in whichl Figure 1 is a vertical section of my invention taken in the line n: :v in iig-2, and

Figure 2 is a horizontal sectionv of the same, taken in the line y y in fig.

Figure 3 is a plan view of a modification. l i

Similar letters of reference indicate like parts.

In the accompanying drawings, A represents thestove or furnace to which the heat-radiator B is attached. The radiator consists inv a chamber or shell, B, through which the hotgases from the stove Aare passed before vreaching the main ilue or pipe C, and this heating-surface is largely 'increased by ues d d, which run vertically .through the chamber B.

The chamber B is provided with the escapes ef, which lead into thc main pipe C; the escape cbeing placed Iat its upper end, (as shown in fig. 1,) and the escape fat its lower end. The heater or radiator B is usually placed immediately in the rear of the stove A, and connected thereto by a short pipe, g, at its hpper end, so thatV both are employed to heat a single room.; but by lengthening out the connecting-pipe g, so as to carryiit through a partition-Wall, the sto've A'may be used for heating one room), while the heater B is set oli' into an adjoiningroom on the same lfloor.

But to make the heater more adaptable generally, so that 'it will accommodate itself to all requirements and conditions, it is provided with a central pipe, I, (tig. 1,) the upper endof which terminates within the chamber' B, near its top, while its lower end opens out through the bottom of the chamber, but is closed, by a cap, z',

when not in use.

The upper escape e is provided with a damper,

Its operation is as follows: When a direct draught is required, the damper L is opened, and the heat from the stove merely passed through the upper end of thc heater, but', by closing the damper h, the chamber B is filled with hot gases, which v,can only escape'intc the tlue C from the bottom ofthe chamber B, bymeansof escapef, and by this means the draught from the chamber B is kept up by the colder gases, which settle at the bottom of the chamber. '.lhe actiou'is'the same when the heater is placed in a room above the stove, as, when the cap z' has been removed frompipe I, and used to close pipe y, and the lower end of pipe I connected with the stove, the pipe I discharges the hot gases from the stove into the upper end of the chamber B.

The Hnos ol d have nocommunication with the inside ofthe chamber B. I

Cold air below the heater is drawn into them, and, becoming heated, flows out at the top.

Fig. 8 shows a modication in the form of the'shellB, to allow the heater to occupy less space when used in the same room with the stove A. Thisl modification consists in giving the side next to the stove a concave form, as shown by 77,- k, so that the stove and heater, as a whole, are more compact in form. In the view shown (tlg. 1,) the stove A has but one escape, g, but two can be used, (an upper and lower escape, similar to escapes e undf, in the heater,) as ordinarily. But two esca-pe'pipes for the stove are of importance only when the heater is used in a separate room.

This radiator has been used, and found to give a very satisfactory result.

What I claim as my invention, and desire to secure by Letters Patent, is-

The shell B, ilues d d, pipes C, e, f, g, l, and damper it, all constructed and arranged as herein shown, and for the purpose described.
